Sections, paragraphs, lists and lines

What it looks like

What you type

Start your sections with header lines:

New section

Subsection

Sub-subsection

== New section ==
=== Subsection ===
==== Sub-subsection ====

Categories

Use categories and sub-categories to organize the wiki. Add a category to your page and the page will show up on that category page.
For a subcategory you must do a little more work. A subcategory turns a category into a subcategory.

To create a subcategory you must already have your 'top' category.

Visit the page that will be in the subcategory.

Edit the page and add in Category:My Subcategory

Save the page, scroll to the bottom, and click on 'My Subcategory'

Now add this page to the 'top' category by adding Category:top category and saving.

A single newline
has no effect on the layout.
These can be used to separate
sentences within a paragraph.
Some editors find that this aids editing
and improves the diff function.

But an empty line
starts a new paragraph.

A single [[wikipedia:newline|newline]]
has no effect on the layout.
These can be used to separate
sentences within a paragraph.
Some editors find that this
aids editing and improves
the ''diff'' function.
But an empty line
starts a new paragraph.

You can break lines
without starting a new paragraph.

You can break lines<br/>
without starting a new paragraph.

Lists are easy to do:

start every line with a star

more stars means deeper levels

* Lists are easy to do:
** start every line with a star
*** more stars means deeper levels

This is primarily for displayed material, but is also used for discussion on Talk pages.

: A colon indents a line or paragraph.
A manual newline starts a new paragraph.

IF a line starts with a space THEN
it will be formatted exactly
as typed;
in a fixed-width font;
lines won't wrap;
ENDIF
this is useful for:
* pasting preformatted text;
* algorithm descriptions;
* program source code
* ASCII art;
* chemical structures;

Automatically hide namespace: Village pump.
<p>The server fills in the part after the | when you save the page. Next time you open the edit box you will see the expanded piped link. A preview interprets the abbreviated form correctly, but does not expand it yet in the edit box. Press Save and again Edit, and you will see the expanded version. The same applies for the following feature.
</td>

Automatically hide stuff in parentheses:
[[kingdom (biology)|]].

Automatically hide namespace:
[[Wikipedia:Village pump|]].

</td></tr>

When adding a comment to a Talk page,

you should sign it. You can do this by
adding three tildes for your user name:

In the URL all symbols must be among: A-Z a-z 0-9 ._\/~%-+&#?!=()@ \x80-\xFF. If a URL contains a different character it should be converted; for example, ^ has to be written %5E (to be looked up in ASCII). A blank space can also be converted into an underscore.

Images

Only images that have been uploaded to this Wiki can be used. To upload images, use the upload page. You can find the uploaded image on the image list

A picture: [[Image:Wiki.jpg]]

or, with alternate text (strongly encouraged)

[[Image:Wiki.jpg|GT/GMC]]

Web browsers render alternate text when not displaying an image -- for example, when the image isn't loaded, or in a text-only browser, or when spoken aloud. See Alternate text for images for help on choosing alternate text.

Clicking on an uploaded image displays a description page, which you can also link directly to: Image:Wiki.png

[[:Image:Wiki.png]]

To include links to images shown as links instead of drawn on the page, use a "media" link.

Character formatting

What it looks like

What you type

Emphasize, strongly, very strongly.

These are double and triple apostrophes, not double quotes.

''Emphasize'', '''strongly''',
'''''very strongly'''''.

You can also write italic and bold
if the desired effect is a specific font style
rather than emphasis, as in mathematical formulae:

F = ma

However, the difference between these two methods is not very important for graphical browsers, and many people choose to ignore it.

You can also write <i>italic</i>
and <b>bold</b> if the desired effect is a
specific font style rather than emphasis, as
in mathematical formulas:
:<b>F</b> = <i>m</i><b>a</b>

A typewriter font for technical terms.

A typewriter font for
<tt>technical terms</tt>.

You can use small text for captions.

You can use <small>small text</small>
for captions.

You can strike out deleted material

and underline new material.

You can <strike>strike out deleted material</strike>
and <u>underline new material</u>.

The latter method of superscript can't be used in the most general context, but is preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.

HTML Tables

Don't bother, there is nothing; but hopefully someone will do a bit of work here as tables can be very useful in conveying a structure which I call, provisionally, the Holistic Knowledge Base.

The need I feel is about classifying (grouping) subjects and subcategories of descending levels. A simple list like the list of P2P Domains (http://p2pfoundation.net/The_Foundation_for_P2P_Alternatives) is inadequate. It can not suggest "neighborhood" relations, for example, between certain groups of subjects. Janosabel 10:43, 26 September 2011 (UTC)

Templates

Some text on a page may correspond in the edit box to just a reference to another page, in the form {{name}}, referring to the page "Template:name". This is called a template. For changing that text, edit that other page. Sometimes a separate edit link is provided for this purpose. A convenient way to put such a link in a template in Wikipedia is with wikipedia:Template:ed.

Page protection

In a few cases the link labeled "Edit this page" is replaced by the text "Protected page" (or equivalents in the language of the project). In that case the page can not be edited.

Separating edits

When moving or copying a piece of text within a page or from another page, and also making other edits, it is useful to separate these edits. This way the diff function can be usefully applied for checking these other edits.
